Specification of Letters Patent. Patentd Tu-11'@ 20, 1922.

Application led August 26, 1919. Serial Nvo.. 319,915.

To all whom t may concern.'

Be it known that l, JOHN J. OREILLY, a. citizen ot the United States ot America, residing at the borough ot Brooklyn, county of Kings, city and State ot New York7 have invented certain new and useful improvements in Pipe-Bending Devices, oi which the following is a specification.

This invention relates to pipeV bending devices and has tor its primary object to provide a very simple and serviceable means whereby pipes or conduits, such as aie used in the installation of electric circuits during the erection ot' a building, may be easily and quickly bent in order to enable the pipe or conduit to be properly laid or extended in the desired direction;

sion oi a pipe bending device7 as above characterized, which may be manufactured and sold at relatively small cost. and can be easily and quickly arranged in position tor use or removed and readily transported 'from place to place. A v l With theV above and other objects in view, tlie invention consists in the improved pipe 'bending device above referred to and in the form', construction and relative arrangement of its several parts, as will be hereinafter more fully describet, illustrated in the accompanying drawing, and subsequently incorporated in the subjoined claims.

In the drawing wherein l have shown several practical embodiments oi my invention:

Fig.v l is a side elevation showing the rpipe bendingdevice in the form of a single metal casting operatively arranged upon a beam Vflange;

Fig. 2 is an end elevation showing a reducing member associated with the bending device, and illustrating` in dotted lines pipes of different sizes arrano'ed Ain position to be bent; y

Fig. 3 is a side elevation illustratingl auother means for securing the bending device manner. f

in position tor use; Fig. 4 is an end elevation illustrating an alternative embodiment of the invention; and

ig. cation. i

,eferring in detail to the drawing, and more particularly to Figs. l and' 2 thereof,

5 is an elevation of a further modifi- 5 designates the body'otl the` pipe bending device, which, as herein shown7 is inthe form of a single metal block or casting, preferably, though not necessarily, of rectangi'i'lar shape'. This metal casting 5' is provided on onev side with a longitudinally extending `channel or recess 6, the inner portion of which is reduced in width as at "7 by the longitudinally extending shoulder 8 which, in the illustrated construction, projects downwardly from the top wall of the recess (di. Thus there is provided two longitudinal channels or recesses opening upon the oppo site ends of the block or casting which are adapted to receive pipes of vrelatively different diameters as indicated at Y l On the opposite side tace of the blocker casting. 5, a relatively'wide longitudinally extending channel 9 is formed for the purpose` oit' receiving' pipes of larger sizes lthan those indicated at P. i l0, in the forni of an angle bar, maybe insei'tedinto this cliii'iinel. as shown in Fig. 2, so as to' reduce thev area thereof in accordei reducing member ance with the diameter of the pipefto'be Y these reducingv members kmay be provided and assembled together within the channel 9 when a further reduction in the area loi.:v

said channelis necessary.

ln the lower portion'of the block or casit-Y ing' 5, below the channels 6 and 9. agroove or recess l1, is formed andy extends in direction'at right angles to said channels. This bent.v It will be understood that :several of l` groove is adapted to receive' the flange F of of the iiange F and 'thus prevent tiltingfoi' rocking movement of the device upon the beam. bending device upon the fixed support in the manner shown in' Fig. l the pifpefi'nay be 4readily engaged in anyone oi" Atherecesses or channels 6, .7 or9, andbent over the end tace of theblock or castin'gin the desired In Fig. 3 of the dra-wing, I have indicated Having mounted for arranged theV another means for securing the bending' gagement in the block or casting and is adapted to be adjusted through an opening bored in a plank F engaged in the groove or recess 11 of the bending block. It is to be understood, however, that when the holding screw 13 is employed, if desired, the lower flange 12 of the bending block may be eliminated or the screw may be adjusted through an opening in said Harige and engaged in the opening of the board or plank F when arranged beneath the base flange of the block.

In Fig. 4 of the drawing I have disclosed an alternative Vconstruction of the device wherein the bending block consists of the upper and lower sections 141 and 15 respectively, said upper section having a reduced portion 16 and the lower' section being provided with a central upwardly extending portion 17, the upper faces of its lower sec-- tion at opposite sides of the extension 17 beingdisposed in different horizontal planes. A sleeve 18 extends upwardly from the cen- Ytral extension 17 of' the lower block section and in this sleeve a clamping screw 19 has threaded engagement, the lower end of said screw'being threaded in the block section 15 asl indicated at 20. The sleeve 18 is provided in its outer surface with a keyway 21 to receive a key on the plate 22. This plate Y is provided at diametrically opposite points with lugs 23 to seat in recesses formed in the upper surface of the block section 14. Thus this block section is securely held against turning movement upon the sleeve 18. By means of the screw 19, the block sections may be mounted upon the beam, boardY or other fixed object. T he upper block section 14 may then be adjusted upon the sleeve 18 relative to the lower section 15 so as to provide channels or recesses at opposite sides lofthe desired width. Thus it will be ap- 1 parent that if the position ot the section lit still another' form of the invention wherein Vtlie'bending device is arranged upon one flange oi the beam B as in Fig. 1, and upon the other HarigeV of this beam, a clamping Y member 24 is positioned. A screw 25 has a section provided with left hand screw threads 26 engaged in the clamping member 2li, while the end of the screw is provided with right hand threads 27, which are engaged in the bending block 5. lt will thus be apparent that by adjusting this screw, the block 5 and member 24n1ay be moved towards each other and securely clampedupon the opposite flanges of the beam B, and by reversing the rotation of the screw the parts may be easily and quickly disengaged from said flanges and the device removed.

F rom the foregoing description considered in connection with the accompanying drawing, the construction and manner of use ot the several illustrated embodiments of the invention will be clearly and fully understood. In view of the very simple construction of the device it will be apparent that my invention may be manufactured and sold at comparatively small cost, and as it may be easily transported Afrom place to place, the device is of great utility in the laying of lead pipe or conduits during the erection of buildings 'for the purpose of re cei ving electrical circuit wires. I have herein disclosed several forms of my improved pipe bending device, which consider very practical for the intended purl pose. Nevertheless it is to be understood that the invention may also be exemplified in numerous other alternative constructions, and I therefore reserve the privilege ofV` adopting all such legitimate changes as may be fairly embodied within the spirit and scope oit' the invention as claimed.
